Analysis on high yield,stable yield and adaptability of national authorized wheat Hemai 22
To identify the yield characteristics of Hemai 22,this study used the data of regional test and production test of water area group in the north of Huang-huai winter wheat area from 2015 to 2018,and the high yield,stability and wide adaptability of Hemai 22 were systematically analyzed and comprehensively evaluated by variance analysis,coefficient of variation,high stability coefficient,rate of yield-increasing point and degree of adaption.The results showed that in 2015 to 2016,the yield of Hemai 22 was slightly lower than that of the control variety Jimai 22,and the yield reduction was not significant.In 2016 to 2018,the yield of Hemai 22 was significantly higher than that of the control variety Jimai 22,showing better production performance.In 2015 to 2018,the yield coefficient of variation and high temperature coefficient of Hemai 22 were in the forefront of the tested varieties,and had good stability and high yield.The average fitness of Hemai 22 in 3 years was equivalent to that of Liangxing 99 and Jimai 22.Except for the low yield point rate of Hemai 22 in 2015 to 2016,the yield increase point rates in 2016 to 2018 reached 89.5%and 91.7%,respectively,indicating that it had good adaptability in multiple environments.The comprehensive analysis showed that Hemai 22 had high yield,stable yield,wide adaptability,multi-resistance,high quality and other excellent traits,and had high promotion and utilization potential in the northern ecological area of Huang-huai winter wheat region.
